されている。2. Description of the Related Art A surface protective film having an adhesive layer formed on one side of a base film is widely known and is used for surface protection of a synthetic resin plate such as an acrylic plate or a metal plate such as a stainless plate.

したものが知られている（例えば、特開昭５３−１１２
９８３号公報及び特開平３−４７８８６号公報参照）。As a surface protective film of this type, an ethylene-vinyl acetate copolymer or a linear low-density polyethylene is used as a base resin on one surface of a base film such as polyethylene, and a tackifier is contained therein. It is known that an adhesive layer is formed (for example, JP-A-53-112).
983 and JP-A-3-47886).

る。However, when such a conventional surface protection film is attached to a resin plate or a metal plate, good initial tackiness can be obtained, but the adhesive strength with time after application is enhanced, and the surface protection film is later applied. It cannot be easily peeled off from a resin plate or a metal plate, and the peeling work requires time and labor, and if peeled off quickly, adhesive residue may remain or the base film may be broken.

がれて、表面保護フィルムの機能を全うできなくなる。In particular, a resin plate such as an acrylic plate is often processed by heating and pressing with a surface protective film attached, and the above phenomenon becomes remarkable under such a high temperature. If the initial adhesive strength is set to be low in order to suppress this, the surface protective film will be spontaneously peeled off at the time of application or during the distribution process, and the function of the surface protective film cannot be fulfilled.

しないことを見出した。The inventor of the present invention has found that an ethylene-vinyl acetate copolymer is used as a base resin as an adhesive layer formed on one surface of a substrate film, and a specific aromatic modification as a tackifier is added to the base resin. It has been found that when a resin composition containing a terpene resin is used, good initial tackiness can be obtained, and further, the adhesive strength with time after sticking to a resin plate does not accelerate even at high temperature.

That is, in order to improve the function, the acrylic plate may be surface-coated with an antistatic agent, a weather resistance improver, a curable paint, a printing ink, etc. after the surface protective film is peeled off. A thin film that cannot be seen by the eye is formed on the surface of the acrylic plate after the protective film is peeled off.If surface coating is applied to the surface of such an acrylic plate, the problem that the surface coating agent cannot be applied uniformly I knew it was.

It is an object of the present invention to provide a surface protective film for an acrylic plate, which has no stain such as adhesive residue or fogging on the surface and which can uniformly apply various surface coating agents to the surface of the acrylic plate.
